Thin film - magnet memory device with communication function and marketing management system and manufacturing step - management system with the use of the thin film - magnet memory device

摘要

A thin film - magnet memory device comprises an antenna section (4), of the radio waves into the exterior of the thin film - magnet memory device which transmits and receives from there. An inductive wiring (5), which forms the antenna section (4), has a metal wiring (6) and a magnetic film (7), the corresponding to an under side section of the metal wiring (6) or a bottom side and the side sections of the metal wiring (6) are formed. The magnetic film (7), in an original step in the production of the thin film - magnet memory device, is formed, without that a single manufacturing step is provided, which is provided for this purpose.
